Two people who usually stick together may complain about each other being clingy, but in fact this is not fair at all. A person will behave in different ways when faced with different people in an environment and weather. To say that men are heartless is too one-sided. He talks sweetly in front of you, but when he turns around, he is so cold and uncaring. In fact, it is easy to understand. When we get along, we can see each other and feel each other. From the various signals conveyed by touch, taste and smell, men and women will become caring for each other. But the scenes suitable for lingering after separation have changed, and face-to-face is no longer practical. Everyone is more willing to show their ideal side, no matter whether it is good or bad. Hot and cold may be inner trends, but the ordinary side is idealized.
